FRANK H. BARBER, OF HOLYOKE, MASS., ASSIGNOB OF ONE-HALF TO THE GEORGE E. DICKINSON PAPER COMPANY, OF SAME PLACE.

SPOOL-WINDER.

SPECIFICATION forming part of Letters Patent No. 327,511, dated October 6, 1885.

Application filed April 3, 1835. Serial No. l61,113. (N0 model.)

To aZZ whom it may concern.-

Be it known that I, FRANK H. BARBER, a citizen of the United States, residing at Holyoke,1'nthe county of Hampden and Comm onwealth of Massachusetts, have invented a new and useful Combination Spool-\Vinder, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in spool-winders carrying two spools or cylindrical rolls, upon which paper or other material in long sheets is wound; and the objects of my improvements are to provide a self-contained device upon the spool-shaft which shall automatically equalize the tension and wind the material with equal tightness upon the two spools. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an external view of my invention complete, and Figs. 2, 3, 4, and 5 are detailed views on a larger scale of the various parts thereof.

Similar letters refer to like parts throughout the several views.

In Fig. 1, A is the spool-shaft,which is supported in suitable bearings and revolved by power in the usual manner.

B and B are the two spools,which are loose upon the shaft A, and are driven by the mechanism between them. This driving mechanism consists, first, of a collar-,0, secured to the shaft A by set-screws, and having arms upon two opposite sides, upon which the bevel-pin ions D D freely revolve and, secondly, of bevel-gears E which are loose upon the shaft A and connected with the spools B B. The spools are held in place by a flange, F, fitting the end of the spool and loose upon the shaft, and a collar, G, set-screwed to the shaft, which arrangement prevents lateral motion of the spool, but allows it to revolve independently of the shaft. The spool B is provided with a similar flange and collar. (Not shown in the drawings.)

The result of this construction is that when the shaft A is revolved the collar 0 turns with it, and the pinions D D revolve or have an orbit around the axis of said shaft. If both spools are free to move, the gears E and E bear equally upon the pinions D D, said pinions re main stationary upon their axes, the two gears are revolved at the same velocity as the collar 0, and carry with them the spools B and B. If the spools are winding material upon them and the tension or resistance is the same on each, the result is the same, for the resistance upon the spool B which is communicated to the gear E, and tends to revolve the pinions in one direction upon their axes, is exactly balanced by the pressure of the gear E in the opposite direction, and hence the pinions remain stationary on their axes, but move in space about the shaft A and drive the two 6 spools at equal velocities; but suppose the resistance on spool B exceeds that on B, the pressure of the gears upon the pinions is unbalanced, the pinions rotate and allow the spool 13 to turn slower than the shaft A, and (as all the gearing is in mesh) cause the spool B to turn faster than the shaft A until the balance readjusts itself, which it will in this manner do automatically, and wind the material with equal tightness upon the two spools. 7 5

The construction of the parts in detail is shown more clearly in Figs. 2 to 5, inclusive. In Fig. 2 is shown thespool shaft A, the flange F for the end of the spool, and the collar G, which is secured to the shaft by the set-screw So and prevents lateral motion of the spool without interfering with freedom of revolution. Fig. 3 is a front view of the flange F, showing the projections f f, which fit corresponding slots in the spools, (indicated at b b 8,- in Fig. 4.) In Fig. 5 are shown the details of the driving'inechanism. O is the pinion-collar, secured to shaft A by set-screws c. The pinions D D have a running fit on the arms K K,and are held in place by bolts 8 s and washc ers t. The collar 0 is continued along the shaft on each side by the proj ecting cylindrical portions L, with grooves Z. The gears E Ehave cylindrical projections M M, of proper form to receive said parts L L, and screws m m, 850., 9 5 to enter the grooves Z. This construction keeps the gears in place while the spools are being changed. \Vhcn the spools are in place, they resist the thrust on the gears, so that there is no strain on the screws on in.

On the outer side of the gear E is a cylindrical part, N, over which fits the sleeve 0.

This sleeve has a flange at one end similar in form to the flange F, already described,-which fits the end of the spool B. The sleeve 0 is slotted at 0, and has ears V at each side of the slot, and bolts W for the same, by means of which the sleeve 0 may be securely clamped to the gear E. The connection is further insured by means of the feather or spline-a3. The object of this construction is to allow adj ustment of the sleeve upon the gear to accommodate different lengths of spools. The gear E and sleeve 0 are connected in a similar manner.

2. The combination, with the shaft A, of

the collar 0, secured thereto,and having arms 2 5 K, and cylindrical portions L, provided with grooves Z, the pinions D, adapted to rotate on said arms, the gears E and E, having cylindrical projections M M, fitting over the said portions L, and provided with screws m, en- 0 arms, the gears E and E,meshing with said 5 pinions, and having cylindrical parts N, and the slotted sleeves O and O, splined to said parts N, and having clamping-ears and bolts, whereby the adjustment of the sleeves relative to the gears, to accommodate different 0 lengths of spools, may be effected, as set forth.
